It would be great to have a callback feature in DTM for Adobe Analytics. The callback would fire after data was sent to Adobe Analytics, such as when the s.t() or s.tl() functions are called. The callback would likely reference the "s" object, so that s.clearVars() can be called. This will allow every hit that is sent to Adobe Analytics to start with a clean slate instead of having to use what was on the previous hit. This is especially important for single page applications.
It would be great to have a global callback available, with the option to set one for each rule. These would fire after the next instance of sending data, and would not continue to queue up for subsequent hits.
